Y2Y is working with its partners to promote wildlife overpasses and underpasses with fencing. These make Highway 3 safer for wildlife and people.
What is the threat?
Just north of the Canada-U.S. border, Highway 3 cuts across the Rocky Mountains through the southern portion of Alberta and B.C. This busy road is at the dividing line between Banff National Park and Glacier-Waterton International Peace Park.
Wildlife needs to cross this road to move between the two key protected areas. Nine thousand vehicles travel this artery every day, bringing an increased likelihood of wildlife-vehicle collisions. Some of the costs to society from these collisions are human fatalities and injuries, vehicle damage and higher insurance premiums.
There is also a high cost being paid by wildlife. If we don’t address the problems on Highway 3, large carnivore populations in the U.S. will become isolated from their larger populations to the north. This brings the possibility of extinction.
What is the opportunity?
There are a number of wildlife overpasses, underpasses and fences on Canada’s Trans-Canada Highway through Banff National Park. Research shows these structures significantly reduce wildlife-vehicle collisions.
Implementing these strategies could significantly reduce the barrier to connectivity that Highway 3 presents. This will also save lives and tax dollars.
People and wildlife on Highway 3: By the numbers
|80%||Decrease in wildlife-vehicle collisions in Banff National Park after crossing and fencing were installed|
|140,000+||Animal crossings in Banff National Park that have promoted gene flow between populations|
|$1,323 to $31,405||Cost to society of the average collision along Highway 3|
|$18,123||Average cost to build and maintain a wildlife-crossing structure with fencing|
|8||Average number of wildlife-vehicle collisions each year at Highway 3’s Rock Creek|
What are we doing?
Y2Y has co-published a study that addressed the following questions about Highway 3:
- Where is wildlife successfully and unsuccessfully crossing the road?
- What measure would best support a safe crossing?
- Which is the most cost-effective approach?
Highway 3: Transportation Mitigation for Wildlife and Connectivity identified 31 strategic sites along Highway 3. Rock Creek and Crowsnest Lakes are our top two priority sites. Y2Y is working with the Alberta and B.C. governments to implement appropriate measures at both sites.
Alberta Transportation installed jump-outs and wildlife fencing at the Crowsnest Pass site.
- Jump-outs give animals caught on the highway an escape route
- Wildlife fencing funnels resident bighorn sheep through an existing underpass
In B.C., additional data is needed so crossing structures will be placed in the most beneficial places for wildlife. If you’re traveling in the area, you can use the mobile phone app Road Watch BC to help. The app can be used to record wildlife sightings and road kills.
Who are we working with?
- Miistakis Institute
- Western Transportation Institute
- Volker Stevin
- Road Watch in the Pass
How can you help?
Use Road Watch BC to share observations of local wildlife along highways in the Elk Valley region. This data will help planners determine the best place to build future crossings.
